Evaluation of a commercially available rapid urinary porphobilinogen test [PDF]

, 2011
Background: Demonstration of substantially increased urinary excretion of porphobilinogen is the cornerstone of diagnosing acute porphyria crisis. Because porphobilinogen testing is not implemented on clinical chemistry analysers, respective analyses are
